Abstract : During this period the Principal Investigator wrote six technical papers. Titles are: New directions in parameter adaptive control, Adaptive stabilization of linear systems with unknown high frequency, A smooth algorithm for adaptive stabilization of a discrete linear system with an unknown high frequency gain, A 4(n+1)-dimensional model reference adaptive control for the stabilization of any strictly proper minimum phase linear system with relative degree not exceeding tow and dimension not exceeding phase linear system with relative degree not exceeding two and dimension not exceeding n, Adaptive stabilization of a discrete linear system with an unknown high frequency gain, and A three dimensional universal controller for the adaptive stabilization of any strictly proper minimum-phase system with relative degree not exceeding two.
